Distorting a UMG Font

How would one go about distorting a font on a UMG widget? Sort of like a glitch effect.

In UMG, when making a font material, does the screen position input parameter modify the position of each character of the font? What precisely does it do and how do I use it?

I see that when I hover over it, it “allows the vertices of the mesh to be manipulated in world space by the material.”

if I use this on a UMG widget with a value other than 0, the font doesn’t render. Any suggestions?
Thanks!

Sort of found the answer to my own question.

You have to render the fonts and other widgets to a render texture and manipulate it from there.
